On Khaz Modan:
I bought 28 stacks @ 150g a stack paying 4200 total:
Patch day came..had a guildie prospect and got 30+ epic gems, 92 titanium dust, a ton of other gems.
I sold a total of zero epics the first day...which made me feel like i made a huge mistake.
Surprisingly the big seller from day one was the titanium dust and the green gems. Sold all but 30 of the dust and most of the green gems after day one.
48 hours later the prices normalized and i began to sell the epics as well on the next auction cycle for about 2/3 of what i listed them on day one.
Total results: Made 4642g in profit on top of my 4200g investment. Wish i had bought more.
